CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to, and is a divisional application of, U.S. patent application Ser. No. 13/085,037, filed Apr. 12, 2011, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

The Internet facilitates the sale of goods or services by many different vendors. To purchase goods or services, a consumer often must create an account on many different market sites, and log into each one to peruse the goods and services offered. This approach is time intensive, and it limits the number of markets with which a consumer can interact. As an alternative strategy, a consumer may rely on a service that aggregates sale information from a variety of market sites. This approach is still time intensive, as a search can return thousands of listings and a consumer must examine each to determine whether the goods or services meet the consumer's specifications.

DETAILED DESCRIPTION

The following terms shall have, for purposes of this application, the respective meanings set forth below:

A “marketplace” is a web page, a website and/or other e-commerce application that sells and/or offers for sale goods and/or services.

A “home site” is a website or other application that generates and/or transmits a specification on behalf of a user. In an embodiment, a user may provide information to a home site regarding a search to be performed, an action to take and/or the like.

A “destination marketplace” is a marketplace that receives a specification for processing.

A “specification” is an electronic file or other data structure that defines a product and/or service that is being sought and one or more instructions that, when executed, perform one or more actions in response to locating the product and/or service.

“Processing” means executing one or more instructions of a specification. For example, a marketplace may process a specification by performing a search of a database or other storage medium associated with the marketplace that is defined in the specification.

A “command block” may be one or more instructions that define an action to perform. For example, a command block may include one or more instructions for performing a search of a marketplace.

An “origin block” is one or more pieces of information identifying and/or corresponding to a home site, a user and/or the like. For example, an origin block may include a URL identifying a home site.

A “routing block” is one or more instructions for transmitting a specification to a destination marketplace. In an embodiment, a routing block may include one or more instructions for a destination marketplace to use to forward the specification to one or more other marketplaces.

The Internet offers consumers a variety of different marketplaces. In an embodiment, individual marketplaces may be considered as a single Internet marketplace with highly distributed components. The components may appear incompatible because of differing arrangements and implementations; however, the components may have similar functions relating to a buying and selling model. For example, each component may allow a consumer to search for an item, purchase an item, bid on a good and/or a service, and/or the like. Table 1 illustrates a comparison of exemplary characteristics of an auction site, a retail site and a project site according to an embodiment.

TABLE 1 Action Auction Site Retail Site Project Site Search postings X X X Create postings X X Place bid/purchase X X X Accept bid X X Reject bid X X Watch price X X

Because different marketplaces operate similarly, a single specification may be generated by a user and may be executed by many marketplaces without modification. In an embodiment, a specification may be generated using a domain-specific language (DSL). A DSL is a programming construct that uses natural language words, phrases and/or portions thereof to describe one or more actions a program should perform. In an embodiment, the words that are used in a DSL may directly correspond to program methods, which may make implementing an interpreter that can parse the DSL and execute commands relatively straight-forward.

FIG. 1 illustrates an exemplary specification 175 according to an embodiment. As illustrated by FIG. 1, a specification 175 may include one or more command blocks 100. In an embodiment, a DSL may be used to define one or more command blocks of a specification. In an embodiment, a command block may include one or more key-value pairs. A key may be an instruction drawn from the DSL. A value may be a parameter of the instruction. For instance, an exemplary instruction may be “ftp_to:”, and an exemplary value may be “ftp.somesite.com.” A command block having this key-value pair may instruct an interpreter to send a file to the destination represented by “ftp.somesite.com” using the FTP protocol.

In an embodiment, a command block may include one or more instructions for logging into a user account, performing a search and/or the like. In an embodiment, a command block for performing a search may include a search term identifying the good(s) and/or service(s) that are being sought. In an embodiment, a command block for performing a search may include a minimum price, a maximum price, product information, such as make, model, color and/or the like. For example, FIG. 1 illustrates a command block 100 that may be used to search projects described using “java”, “.net” or “ajax.” As another example, the following command block may be used to search a retail site for vacuum cleaners under $500 from any manufacturer:

Search:

-   -   Item: vacuum cleaner     -   Price: <500     -   Make: any

In an embodiment, a specification having a command block for performing a search may include one or more instructions for performing one or more actions on one or more results of the search. Exemplary actions may include refining the search, placing a bid on a good and/or a service, purchasing a good and/or a service, emailing the results to a user and/or the like. For example, FIG. 1 illustrates exemplary instructions 105 for emailing a user the top ten results of the search. As illustrated by FIG. 1, an email including the top ten results may be sent to the email address useralpha@amicrowork.com with the subject line “You might want to bid on these projects.” These instructions may send only the first ten items in the search results to the specified email address using the given subject line. Additional and/or alternate instructions may be used within the scope of this disclosure.

In an embodiment, a specification may include an origin block. An origin block may include information about a home site, a user and/or the like. In an embodiment, an origin block may be used to validate the existence of a user, and facilitate the transfer of information back to the home site.

In an embodiment, an origin block may include an identifier of the home site, such as a uniform resource locator (URL) and/or the like. For example, referring to FIG. 1, the origin block 110 includes a URL 115 identifying the home site. The origin block may include a user identifier that uniquely identifies the user. In an embodiment, a user identifier may be a session code, which may help prevent spoofing of identifiable user information, such as a user name, an account number and/or the like. In an embodiment, a user identifier may be encrypted so that it can only be interpreted by the home site. FIG. 1 illustrates an exemplary user identifier 120 according to an embodiment.

In an embodiment, an origin block may include a verification URL. A verification URL may be a URL that a destination marketplace can use to request verification from a home site that sent the specification. FIG. 1 illustrates an exemplary verification URL 125 according to an embodiment. In an embodiment, a specification may include a digital signature that may be used to perform verification. For example, a marketplace that receives a specification may transmit the digital signature that is embedded in the specification to the site associated with the verification URL. In response, the destination marketplace that received the specification may receive a verification of authenticity or a denial of authenticity from the home site. In an embodiment, a third party may perform the verification process. In an embodiment, if a verification of authenticity is received, the specification may be processed. If a denial of authenticity is received, the specification may not be processed.

In an embodiment, an origin block may include a Universal Unique Identifier (UUID). A UUID may be a unique identifier associated with a specification. FIG. 1 illustrates an exemplary UUID 130 according to an embodiment. A UUID may prevent a destination marketplace from executing multiple copies of the same specification. Since all copies of a specification may have the same UUID, a destination marketplace that receives multiple copies of a specification may be able to ignore all but the first copy that is received. In an embodiment, a UUID may allow a database of specifications, such as a database associated with a home site or another marketplace, to verify the source of the specification without the risk of naming collisions. In an embodiment, an origin command block may include a timestamp indicating the time at which the corresponding specification was created. In an embodiment, a timestamp may include a date, a time, a time zone and/or the like. FIG. 1 illustrates an exemplary timestamp 135 according to an embodiment.

In an embodiment, a specification may include a routing block. In an embodiment, a destination marketplace may have an associated database or other storage medium that stores names, descriptions, URL addresses and/or the like associated with the other marketplaces. A marketplace may forward the received specification to one or more of these marketplaces according to one or more instructions included in the routing block.

FIG. 1 illustrates an exemplary routing block 155 according to an embodiment. As illustrated by FIG. 1, a routing block 155 may include information about one or more marketplaces that have already received and processed the specification. In an embodiment, a routing block may include a URL or other identifier 140 a-N of one or more visited marketplaces. A visited marketplace may be a marketplace that has already received the specification. In an embodiment, a routing block may include a timestamp 145 a-N indicating the date, time and/or the like of when the specification was received by each visited marketplace. For example, referring to FIG. 1, the specification visited the marketplace http://someothemlarket.com/verify on Monday, Apr. 26, 2010 at 11:02:32 EDT. In an embodiment, a routing block may include an indication 150 a-N of whether each visited marketplace verified the specification.

As illustrated by FIG. 1, a routing block may include an indication 160 of how long or to how many marketplaces the specification is to be forwarded. For example, an indication may be an amount of time during which a specification should be forwarded, such as one day, one week, one month and/or the like. Additional and/or alternate amounts of time may be used within the scope of this disclosure. After the time period has ended, the specification may not be further forwarded.

In an embodiment, an indication 160 may be a number of times the specification should be forwarded. For example, referring to FIG. 1, the routing block 155 includes an indication 160 that the specification 175 should be forwarded four times. After the specification 175 has been transmitted four times, it may not be forwarded again.

In an embodiment, a routing block may include an indication of a destination marketplace to which the specification should be forwarded. The indication of a destination marketplace may be a name, URL and/or the like associated with the destination marketplace. As illustrated by FIG. 1, the specification 175 is to be forwarded to the marketplace identified by the URL http://projectsrus.com 165.

In an embodiment, a routing block may include an indication of a marketplace type. A marketplace type may be a category associated with a marketplace, a description of the goods and/or services offered by a marketplace, a purpose associated with a marketplace and/or the like. In an embodiment, an indication of a marketplace type may indicate the type of marketplace that should process the specification. For example, FIG. 1 illustrates a marketplace type 170 of “freelance” and “project.” In an embodiment, if a specification is forwarded to a marketplace that does not satisfy the marketplace type, the marketplace may not process the specification. In an embodiment, if the marketplace does satisfy the marketplace type, the marketplace may process the specification.

FIG. 2 illustrates an exemplary method of processing a specification according to an embodiment. FIG. 3 illustrates an exemplary system for processing a specification according to an embodiment. As illustrated by FIG. 3, a home site 300 may include a user interface 305, a database 310, a specification generator 315 and/or a transfer agent 320. In an embodiment, the database 310 may be in communication with the user interface 305, the specification generator 315 and/or the transfer agent 320.

In an embodiment, a user may enter 200 information via a user interface 305. In an embodiment, the user interface 305 may be provided as a webpage or other graphical user interface on a computing device. In an embodiment, a user may enter 200 information regarding a search to be performed. For example, a user may enter 200 information about the good(s) and/or service(s) to search for such as a description, a quantity, a color, a model, a make, a geographic region, a price and/or the like. Additional and/or alternate information may be used within the scope of this disclosure.

In an embodiment, a user may enter 200 information regarding one or more actions to take on the results of the search. In an embodiment, a user may enter 200 information regarding a destination marketplace. For example, a user may identify a marketplace by name, URL address, category of goods and/or services offered, purpose of the marketplace and/or the like. In an embodiment, a user may enter 200 information using one or more drop-down menus, radio buttons, checkboxes, free-form text entry fields and/or the like. Additional and/or alternate menus and/or fields may be used within the scope of this disclosure.

In an embodiment, the information that a user enters may be stored 205 in the database 310 associated with the home site 300. The entered information may be used by the specification generator 315 to create a specification. In an embodiment, a specification generator 315 may be a self-contained component of the home site 300. A specification generator 315 may include hardware, software and/or a combination of hardware and software. In an embodiment, a specification generator 315 may receive information provided by a user from the user interface 305 and/or a database 310. The specification generator 315 may use this information to automatically generate 210 a specification having an origin block, a command block, a routing block and/or the like.

For example, a user may want to search for a car. The user may specify that the car should be a black, 2000-2008 Honda Civic. The user may specify that the website http://www.carworld.com should be searched, and that the life of the search should be two marketplaces. The user may indicate that the top ten results from each marketplace should be emailed to his personal email account with the subject line “Honda Civics for Sale.” In an embodiment, the specification generator 315 may use this information to generate 210 the specification shown in FIG. 4A.

In an embodiment, a user may specify that the specification should be transmitted to a certain marketplace. The specification may include an indication of this marketplace, such as a corresponding URL address. In an embodiment, a user may not specify a marketplace. In this case, the specification generator 315 may access information regarding one or more marketplaces from the database 310. In an embodiment, the database 310 may store information regarding one or more marketplaces with which the home site 300 is in communication. These marketplaces may include marketplaces that have been previously sent specifications, marketplaces affiliated with the home site, popular marketplaces and/or the like. The specification generator 315 may include an indication, such as a URL address, corresponding to one or more of the marketplaces from the database 310 in the specification.

In an embodiment, the transfer agent 320 may receive a specification from the specification generator. The transfer agent 320 may be a self-contained component of the home site. A transfer agent 320 may include hardware, software and/or a combination of hardware and software. In an embodiment, the transfer agent 320 may transmit 215 the specification to one or more marketplaces via a network 325, such as the Internet. In an embodiment, the transfer agent 320 may transmit 215 the specification to one or more destination marketplaces 330 that are identified in the specification.

In an embodiment, a destination marketplace 330 may receive the specification from the home site 300. In an embodiment, a receiver 335 associated with the destination marketplace 330 may receive the specification. If the specification is encrypted, the receiver 335 may decrypt the specification. A receiver 335 may be a self-contained component of a destination marketplace 330. A receiver 335 may include hardware, software and/or a combination of hardware and software.

In an embodiment, the receiver 335 may transmit the received specification to a parser 340 associated with the destination marketplace 330. A parser 340 may be a self-contained component of a destination marketplace 330. A parser 340 may include hardware, software and/or a combination of hardware and software. A parser 340 may parse 220 the text of the specification to identify program elements and confirm that the elements are expressed in the correct syntax.

In an embodiment, the parser 340 may transmit a specification that has been parsed to an interpreter 345 associated with a destination marketplace 330. An interpreter 345 may be a self-contained component of a destination marketplace 330. An interpreter 345 may include hardware, software and/or a combination of hardware and software. In an embodiment, an interpreter 345 may read the instructions contained in a specification, and may execute the instructions. For example, the specification identified in FIG. 4A may be sent to the destination marketplace 330 associated with the URL http://www.carworld.com. The specification may be received by a receiver 335 associated with the destination marketplace 330, and it may be transmitted to a parser 340 associated with the destination marketplace 330. The parser 340 may parse 220 the specification, and transmit it to an interpreter 345 associated with the destination marketplace 330.

In an embodiment, an interpreter 345 associated with a destination marketplace 330 may authenticate 225 a received specification. In an embodiment, the interpreter 345 may send the digital signature included in the received specification to the verification URL included in the specification. In response, the destination marketplace 330 may receive a verification of authenticity or a denial of authenticity from the home site 300. In an embodiment, if a verification of authenticity is received, the specification may be processed. If a denial of authenticity is received, the specification may not be processed.

In an embodiment, the interpreter 345 associated with a destination marketplace 330 may determine whether the destination marketplace satisfies one or more requirements of the specification. For example, as discussed above, a specification may include a marketplace type. The interpreter 345 may determine whether the destination marketplace satisfies the marketplace type. For example, if a marketplace type associated with a specification is “automobiles,” but the destination marketplace includes a listing of available technology jobs, then the destination marketplace may not satisfy the marketplace type. In an embodiment, if the destination marketplace satisfies the marketplace type, the specification may be processed by the destination marketplace. Conversely, if the destination site does not satisfy the marketplace type, the specification may not be processed by the destination marketplace.

In an embodiment, the interpreter 345 may process 230 the specification. For example, the interpreter 345 associated with the URL address http://www.carworld.com may search its inventory for black, 2000-2008 Honda Civics. In an embodiment, the interpreter 345 may perform the one or more actions identified in the specification. For example, the interpreter 345 associated with the URL address http://www.carworld.com may send an email with a subject line “Honda Civics for Sale” to the address user@address.com. The content of the email may be the top ten search results from the search of the destination marketplace associated with the URL http://www.carworld.com.

In an embodiment, the interpreter 345 associated with a destination marketplace 330 may modify 235 the specification. For example, the interpreter 345 may update the routing block. The interpreter 345 may modify 235 the specification to indicate that the associated destination marketplace 330 has already processed the specification. In an embodiment, the interpreter 345 may modify 235 the specification to identify whether the specification was verified.

For example, FIG. 4B illustrates how the interpreter 345 associated with the destination marketplace http://www.carworld.com may modify 235 the specification shown in FIG. 4A. As illustrated by FIG. 4B, the routing block may be modified to provide an indication 400 that the destination marketplace associated with URL address http://www.carworld.com has already processed the specification. The routing block may be modified to include a timestamp 405 indicating when the destination marketplace was visited, and an indication 410 as to whether the destination marketplace was able to authenticate the specification. In an embodiment, the interpreter 345 may modify 235 the routing block of the specification to include a new destination marketplace 415. In an embodiment, the interpreter 345 may transmit 240 the specification to one or more destination marketplaces that are stored in the database 350 associated with the destination marketplace 330. For example, the database 350 associated with the destination marketplace 330 may store information regarding one or more other destination marketplaces with which the destination marketplace is in communication. These destination marketplaces may include destination marketplaces that have been previously sent specifications, destination marketplaces affiliated with the destination marketplace, popular destination marketplaces and/or the like.

In an embodiment, a marketplace may include a home site and a destination marketplace. In an embodiment, the home site of a marketplace may generate a specification, and the destination marketplace of the marketplace may process the specification. In an alternate embodiment, a home site may be associated with a different marketplace than a destination marketplace.
